Was using my laptop, I walked away from my Toshiba Satellite C655 and came back to see the screen that says "Windows did not shut down properly. Please hit enter to start windows normally." I did and it went to a blank, black screen. Startup repair couldn't fix the problem and it flashed something that said windows could not be found. I restarted my computer after that and now it just goes to a black screen that shows: BOOTMGR is missing Press Ctrl+Alt+Del to restart. Nothing happens when I do. so looks like windows 7 is gone and now I can't get past that screen when I start my computer.
